MnemoPay Plugin for Hermes Agent

Give Hermes persistent cognitive memory and a micropayment wallet.

Install

pip install mnemopay-hermes

Or drop into your plugins directory:

cp -r mnemopay_hermes ~/.hermes/plugins/mnemopay/
cp plugin.yaml ~/.hermes/plugins/mnemopay/

What It Does

• 15 tools: remember, recall, forget, reinforce, consolidate, charge, settle, refund, balance, profile, reputation, logs, history, dispute, fraud_stats
• 4 prompts: recall-and-decide, agent-status-report, session-start, session-end
• Memory injection: pre_llm_call hook automatically recalls relevant memories and injects them into every prompt
• Auto-remember: post_tool_call hook stores significant tool outcomes as memories
• Session lifecycle: session-start prompt recalls top memories on start, session-end consolidates and saves summary on shutdown

Configuration

The plugin spawns the MnemoPay MCP server (npx @mnemopay/sdk) as a subprocess. Configure via environment variables:

Alternative: MCP Config (No Plugin Needed)

If you just want the tools without hooks, add to your Hermes config:

mcp_servers:
  mnemopay:
    command: "npx"
    args: ["-y", "@mnemopay/sdk"]
    env:
      MNEMOPAY_AGENT_ID: "hermes-agent"

The plugin adds the pre_llm_call memory injection and post_tool_call auto-remember on top of this.
